Module Strategy

Use the following strategy to present this module:

Introduction to Networking Services Design Provide a brief description of a model for designing a networking services infrastructure

In this section:

• Point out that this basic design process is useful for designing a network infrastructure At a high level, it is the process by which all networks are designed, implemented, and managed

• Emphasize that this model is generic in nature Organizations typically customize the model to suit their unique situations and design

methodologies Avoid spending time discussing implementation and management philosophies

• Some students may have good methodology skills Avoid spending too much time on the details of the methodology and avoid getting into a discussion about the relative merits of specific methodologies

• In the subsequent modules, students generate their own designs and strategies Acknowledge that solutions may vary by student

Microsoft Windows 2000 Networking Services Provide an overview of Windows 2000 networking services

In this section:

• Emphasize that this course is based on services and options available in Microsoft Windows 2000 Advanced Server

• Explain that Microsoft Windows 2000 server products offer a number of distinct network technologies and services These technologies address specific organizational needs and have both benefits and limitations

• Point out that designers must understand the organizational objectives to create a networking services design that best meets these objectives

• Avoid going into too much detail in this topic The details come in the modules that follow

• This topic presents a good chance to find out how knowledgeable the students are in each of the technologies and to identify whether students require more background information on any given technology

Translating organizational goals into a design Introduce the criteria used to evaluate and refine a design

In this section:

• Point out the aspects for grouping design decisions and explain that these aspects are aimed at making a design process more consistent and logical

• Discuss each aspect and provide an example of how the aspect applies to

a design

• Emphasize that the aspects are used in subsequent modules to analyze and design a networking solution

Overview

Introduction to Networking Services Design

Microsoft Windows 2000 Networking Services

Translating Organizational Goals into a Design

To develop an effective networking services infrastructure, you must be able to analyze the organizational goals and translate them into specific design strategies

In your networking services design, you must take into account the existing infrastructure You will base all of your design decisions on the existing infrastructure In addition, your design must be easily managed so that the organization is able to maintain the infrastructure operation within design specifications

At the end of this module, you will be able to:

Describe the process for designing the networking services infrastructure

Identify the Microsoft® Windows® 2000 networking services that make up a networking services infrastructure

Describe the design aspects used to translate organizational goals into a networking services design

Slide Objective

To provide an overview of

the module topics and

objectives

Lead-in

When you design a

networking services

infrastructure, you must

follow some general

principles that apply to most

networking scenarios

2 Module 1: Microsoft® Windows® 2000 Networking Services Infrastructure Overview

Introduction to Networking Services Design

The cycle used for deploying networking services into a network consists of three main phases You can further divide each phase of the deployment cycle into specific decisions The characteristics of an organization make each network deployment cycle slightly different

Design

A comprehensive design consists of several essential decisions The selection of networking services is one of the decisions that requires knowledge of the existing infrastructure and current organizational goals

After you select the networking services to include in your design, you must consider how to combine the services You need to combine the networking services to improve the administration and performance of the network

Finally, you must decide on a management strategy that ensures the design specifications are met on a day-to-day basis Your management strategy must also specify actions taken, if any, when the network fails to meet the design specifications

Implement

After your design is created and satisfactorily tested, the network design is ready for implementation During this phase of the process, the network is configured to meet the specifications of the design Management processes are put into place to collect information, and the network operation begins

Manage

During this phase of the process, you begin collecting data on the day-to-day operation of the network The data that you collect allows you to determine which actions are required to maintain the network within design specifications

If the network characteristics significantly differ from the design specifications, you may need to redesign the solution

Slide Objective

To introduce the basic

model of a networking

services design cycle

Lead-in

Although networking

designs vary widely in their

overall structure, you may

notice that all networking

designs have some

common characteristics

Emphasize that the design

phase of the process is the

focus of this course Do not

spend time discussing the

implementation or

management components

Delivery Tip

Ask the students to discuss

their experiences and see

how they fit into this model

Ask the students where pilot

testing may fit into the

deployment process Some

students may place pilot

testing in design, others

may place pilot testing in

implementation

Microsoft Windows 2000 Networking Services

Designing the Network Foundation

Designing Internet Connectivity

Designing Remote Access Connectivity

Creating an Integrated Networking Services Infrastructure Design

Microsoft Windows 2000 Advanced Server offers a number of networking services These services were developed to address specific requirements within

an organization

You can create a networking services solution to fulfill the connectivity needs

of your organization To design a solution, you must translate the goals of your organization into functional requirements and specifications

Each of the networking services implemented by Windows 2000 addresses a different set of requirements Some are fundamental, such as Transmission Control Protocol/Internet Protocol (TCP/IP), which is required when you plan

to implement the Windows 2000 Active Directory™ directory service Other networking services, such as Routing and Remote Access, address more specific needs like providing remote user connectivity

Slide Objective

To introduce network

services based on their

function within a networking

services infrastructure

Lead-in

As part of your design, you

can begin the selection of

networking services based

on the functionality they

provide to an organization’s

network

Delivery Tip

Emphasize the fact that not

all of these services apply to

an organization The

services are designed to

address a specific type of

networking requirement

4 Module 1: Microsoft® Windows® 2000 Networking Services Infrastructure Overview

Designing the Network Foundation

Name?

IP Address

TCP/IP Network

Base Protocol Support: TCP/IP

Networking Services: DHCP, DNS, WINS

The foundation of your networking services design is based upon services that are common to all designs These networking services provide support for an addressing structure, automated client configuration, and name resolution services

TCP/IP

TCP/IP is an industry-standard, vendor-independent routable protocol Many of the services provided in Windows 2000, such as WINS, DNS, Active Directory,

or Internet Information Services (IIS), require TCP/IP

DHCP

For TCP/IP networks, managing TCP/IP configurations manually can be a time-consuming task that is prone to errors DHCP automates and manages the TCP/IP configuration of the computers on the network, including the IP address, subnet mask, default gateway, DNS server addresses, and WINS server addresses DHCP reduces the administrative overhead associated with TCP/IP configuration

DNS

DNS provides domain name resolution within the network This allows computers within the network to use a fully qualified domain name (FQDN), such as www.microsoft.com DNS resolves an FQDN to an IP address FQDNs allow network designers to create meaningful resource names and implement DNS designs for resolving those names DNS resolves FQDNs by querying a DNS database for a matching entry that relates FQDNs to IP addresses

Slide Objective

To highlight the services

that provide an IP

networking infrastructure

Lead-in

Basic networking requires

services that provide critical

functions such as data

transmission, client

configuration, and name

resolution

WINS

One of the most popular peer-to-peer communications application programming interfaces (APIs) is the network basic input/output system (NetBIOS) API Earlier versions of Windows networking used NetBIOS as a communications API As with DNS FQDNs, NetBIOS names must be resolved to IP addresses for network connections to occur WINS is a NetBIOS name resolution service that resolves NetBIOS resource names to IP addresses

In Windows 2000, WINS is needed to support previous clients such as those running Microsoft Windows NT® version 4.0, Windows for Workgroups, or Microsoft Windows 95 without the Active Directory client In addition, any applications that use NetBIOS for peer-to-peer communications rely on WINS for name resolution

6 Module 1: Microsoft® Windows® 2000 Networking Services Infrastructure Overview

Designing Internet Connectivity

NAT

Microsoft Proxy Server

NAT

Proxy Server

The Internet provides tremendous opportunity for organizations to communicate through means previously impossible However, Internet connectivity exposes the private network to risks that were not present when private networks were isolated The Network Address Translation (NAT) protocol and Microsoft Proxy Server 2.0 are two networking services that provide organizations secured access to the Internet

NAT

NAT, a protocol found in the Routing and Remote Access feature of Windows 2000, simplifies the Internet connection of all computers that are on a single subnet network NAT provides Internet connectivity in solutions where simplistic implementation and management are necessary NAT provides methods of securing the private network that are adequate to protect resources that are not available to Internet users

Microsoft Proxy Server

Microsoft Proxy Server 2.0 allows organizations to control the exchange of information between their private network and the Internet You can include Proxy Server like a firewall in your design to protect the private network In addition, you can include Proxy Server in your design to improve the performance of Internet access through existing connections You can enhance the availability of your Proxy Server solution by including Proxy Server arrays

Slide Objective

To highlight the network

services that help manage

access to the Internet

Lead-in

NAT and Proxy Server

provide a solution for

Internet connectivity by

helping to manage access

to the Internet

Emphasize that the services

covered in this course are

not directed to an

organization of a particular

size Some students may

come from an organization

that does not use a service

such as NAT
